Assessment of stress and self-efficacy for the NIH Toolbox for Neurological and Behavioral Function

Background and Objectives: The NIH Toolbox for Neurological and Behavioral Function assessment battery contains measures in the domains of cognitive function, motor function, sensory function, and emotional health. It was designed for use in epidemiological and clinical trials health-related research. Design: This paper describes the first phase of instrument development for the stress and self-efficacy subdomain of emotional health. Based on an extensive literature review and expert consultation, 127 measures were initially considered for inclusion in this subdomain, including measures of stress, self-efficacy, emotion regulation, and coping. Results: Several measures, including emotion regulation and measures of coping strategies, did not meet criteria that were a priori established for inclusion. Psychometric properties of the remaining candidate measures were evaluated using data from five independent samples (combined N = 3175). Confirmatory and exploratory factor analyses indicated the Perceived Stress Scale and the General Self-Efficacy Scale each assessed single dimensions. Conclusions: Based on their psychometric performance, these two instruments were selected for inclusion and subsequent national norming for the NIH Toolbox.     

Personality and self-reported use of mobile phones for games.

Mobile phones are popular devices that may generate problems for a section of the community. A previous study using the Eysenck Personality Questionnaire found that extraverts with low self-esteem reported more problems with their mobile phone use. The present study used the NEO FI and Coopersmith Self-Esteem Inventory to predict the self reported mobile phone use of 112 participants. Multiple regression found that people low on agreeableness were more likely to use their mobile phones to play games. The findings imply an interplay between personality traits and excessive or problematic use on mobile phones that is relevant to proposed innovations such as gambling on mobile phones.     

Lesions of the rat nucleus basalis magnocellularis disrupt appetitive-to-aversive transfer learning

Rats with selective lesions of the nucleus basalis magnocellularis (NBM) and sham-lesion control animals were tested in an operant appetitive-to-aversive transfer task. We hypothesized that NBM lesions would not affect performance in the appetitive phase, but that performance would be impaired during subsequent transfer to the aversive phase of the task. Additional groups of NBM lesion and control rats were tested in the avoidance condition only, where we hypothesized that NBM lesions would not disrupt performance. These hypotheses were based, on the argument that the NBM is not necessary for simple association learning that does not tax attention. Both the appetitive phase of the transfer task and the avoidance only task depend only on simple associative learning and are argued not to tax attention. Consequently, performance in these tasks was predicted to be spared following NBM lesions. Complex, attention-demanding associative learning, however, is argued to depend on the NBM. Performance, in the aversive phase of the transfer task is both attentionally demanding and associatively more complex than in either the appetitive or aversive tasks alone; thus, avoidance performance in the NBM lesion group was predicted to be impaired following transfer from prior appetitive conditioning. Results supported our hypotheses, with the NBM lesion group acquiring the appetitive response normally, but showing impaired performance following transfer to the aversive conditioning phase of the transfer task. Impairments were not attributable to disrupted avoidance learning per se, as avoidance behavior was normal in the NBM lesion group tested in the avoidance condition only.     

Measurements, Morality, and the Politics of “Normal” Infant Growth

Although the birth and early life of an infant is similar throughout the world, meanings ascribed to infants differ according to cultural values and beliefs. This essay describes how scholars and healers have come to see the infant as distinct from other types of people, and what implications this distinction carries for how health care is practiced. The first portion of this essay explores how understanding of the infant, particularly the well-accepted notion of “normal” infant growth and development, came to prominence. Drawing from the history of medicine, philosophical thought and colonial practice, this essay demonstrates that the roots of thinking about the infant in terms of his growth are deep and well-defined in North American and European ideologies. The second portion of this essay describes the practical applications and political implications of beliefs about the “normal” infant. In the arena of applied health, policy makers measure infant growth in light of assumptions about the “normal.” A case study of indigenous populations in Irian Jaya, Indonesia, shows that these measurements are highly political. Here government health officials create and manipulate statistics to ensure that indigenous infant health is represented as being below “normal.” The “normal” infant can thus be understood as a subtle and effective construct which, in Irian Jaya, at the least, is used to assimilate indigenous people into the nation-state.     

A computer touch-screen apparatus for training visual discriminations in rats.

We describe an operant conditioning apparatus that uses computerized touch-screen technology and is designed for the versatile and highly controlled testing of rats in a potentially wide variety of behavioral paradigms. Although computer-controlled touch-screen systems have been developed for use with pigeons, monkeys, and humans, analogous technologies and methods have not yet been developed for rats. The development of a touch-screen system for rats could enhance the efficiency of behavioral research with rats, and may offer a unique tool for studying animal learning. In the first test of the utility of the apparatus, 3 Sprague-Dawley rats learned to activate the touch screen only after the touch-screen panel was made slightly movable. These animals then learned to discriminate visual stimuli presented on the computer monitor, but only after the food magazine and pellet dispenser were moved to the rear of the chamber opposite the stimulus display and response window. In a test of the utility of the modified apparatus, 6 Long-Evans rats learned to activate the touch screen and learned one of three different simple discriminations using computer-generated, visually presented stimuli. A basic method for training rats to activate the computer touch screen and for visual discrimination training is described. Results show that rats learned to activate the touch screen and discriminate visual stimuli presented on a computer monitor. Potential applications and advantages of the touch-screen-equipped rat operant conditioning chamber are discussed.     

Stress in Elite Sports Coaching: Identifying Stressors

This paper presents the first in a series of studies exploring coaches’ experiences of stress within the unique culture of world class sport. The purpose of this study was to gain an in-depth account of the stressors encountered by elite coaches in the United Kingdom. Six male and six female coaches with international experience were interviewed. Transcribed interviews were inductively content analyzed by three independent researchers. Ten higher-order themes emerged, demonstrating that coaches experienced a wide range of stressors (e.g., conflict, pressure and expectation, athlete concerns, competition preparation, isolation). Conflict within the organization emerged as a key theme, indicating that communication skills might be important in helping coaches function effectively as part of a wider organizational team. Findings also highlight the importance of psychological skills training for coaches to help them cope with the diverse demands of world class coaching.     

Sensitivity of the informant questionnaire on cognitive decline: an application of item response theory

The Informant Questionnaire on Cognitive Decline (IQCODE) is a formal informant report instrument, originally developed by Jorm and Jacomb (1989; Psychological Medicine, 19(4), 1015). The goal of the present study was to evaluate the range of cognitive decline in which the IQCODE is most sensitive, using item response theory (IRT). Existing data (N = 740) from a sample of community-dwelling older adults was used for this purpose. A 2-parameter model estimating item difficulty and discrimination fit the data best. Additionally, the IQCODE provided the most psychometric information in the range of -0.5 < theta < 1.5, with peak information obtained at approximately theta = 0.4. Based on individuals' latent score (theta) estimates, items on the IQCODE are adequate for use as a screening tool for dementia. Results of the item calibration may be useful for targeted assessment needs, such as the development of short forms.
